The soil and climatic conditions are conducive for the growth of a lot of medical herbs in Kosovo. Mentha longifolia (L.) is native to
Europe, Central Asia and Australia. Lipids, proteins, minerals and essential oils were quantitatively determined from the Mentha longifolia
(L.) growing wild in Germia Park (located in the northeast of Pristina). Total proteins were analyzed, by Kjeldahl method. The total amount
of proteins in the Mentha longifolia (L.) is 8.227 %. Lipids are analyzed by Soxhlet extraction. The total amount of lipids in the Mentha
longifolia (L.) are 5.804 %. Essential oils were isolated using steam distillation. The total amount of essential oils in the Mentha longifolia
(L.) are 0.589 %. The mineral content was studied and analyzed by flame atomic absorption spectrometry. Six elements, sodium,
potassium, calcium, zinc, iron and copper were determined in the Mentha longifolia (L.). The mean levels of sodium, potassium, calcium,
zinc, iron and copper are 509.7 mg kg-1
, 4055 mg kg-1
, 9097 mg kg-1
, 256.7 mg kg-1
, 11841 mg kg-1
, 82.83 mg kg-1
in the Mentha longifolia
(L.), respectively. Iron and calcium are present in large amounts in the Mentha longifolia (L.). The antioxidant activity of essential oil was
evaluated by means of the 2,2-diphenyl-1-picrylhydrazil (DPPH) radical scavenging method. During the analysis of antioxidant activity of
the extracts of Mentha longifolia (L) it has been observed that only H2O extract shows strong antioxidant activity than BHT and BHA
Key words: : Mentha longifolia (L.), essential oil, proteins, lipids, antioxidant activity, DPPH.
